Jackie was great!
Jackie was great! She was helpful and knowledgable. She seemed interested in helping me find exactly what I was looking for. I would highly recommend her.
So far so good!
So far so good! This truck is the nicest truck I have ever driven. The stance, ride comfort and options are top notch. I went from a 2023 High Country that was having drive train issues but had all the creature comforts that you would expect in a top of the line truck. With the lack of confidence in that particular models 10 speed transmission issues, it became necessary to reestablish my confidence in my General Motors product.

I would recommend client manager/sales person Bryan
I would recommend client manager/sales person Bryan Druktenis. He is very professional and friendly. He did not pressure me. Lol. Once l purchased my vehicle(s) he was very helpful in showing me how to set up my features and answered any questions l had when l called. Bryan was my sales person for my Acadia that l traded in for the Yukon.
